Product Description:

Aluminium alloys with a wide range of properties are used in engineering structures. Alloy systems are classified by a number system (ANSI) or by names indicating their main alloying constituents (DIN and ISO).

The strength and durability of aluminium alloys vary widely, not only as a result of the components of the specific alloy, but also as a result of heat treatments and manufacturing processes. A lack of knowledge of these aspects has from time to time led to improperly designed structures and gained aluminium a bad reputation.

One important structural limitation of aluminium alloys is their fatigue strength. Unlike steels, aluminium alloys have no well-defined fatigue limit, meaning that fatigue failure eventually occurs, under even very small cyclic loadings. This implies that engineers must assess these loads and design for a fixed life rather than an infinite life.

Another important property of aluminium alloys is their sensitivity to heat. Workshop procedures involving heating are complicated by the fact that aluminium, unlike steel, melts without first glowing red. Forming operations where a blow torch is used therefore require some expertise, since no visual signs reveal how close the material is to melting. Aluminium alloys, like all structural alloys, also are subject to internal stresses following heating operations such as welding and casting. The problem with aluminium alloys in this regard is their low melting point, which make them more susceptible to distortions from thermally induced stress relief. Controlled stress relief can be done during manufacturing by heat-treating the parts in an oven, followed by gradual cooling—in effect annealing the stresses.

The low melting point of aluminium alloys has not precluded their use in rocketry; even for use in constructing combustion chambers where gases can reach 3500 K. The Agena upper stage engine used a regeneratively cooled aluminium design for some parts of the nozzle, including the thermally critical throat region.

Another alloy of some value is aluminium bronze (Cu-Al alloy).



Aluminium foil acts as a total barrier to light and oxygen (which cause fats to oxidise or become rancid), odours and flavours, moistness, and germs, it is used broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic processing|aseptic packaging) for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods.

Aluminium foil is widely sold into the consumer market, often in rolls of 500 mm (20 in) width and several metres in length.It is used for wrapping food in order to preserve it, for example, when storing leftover food in a refrigerator (where it serves the additional purpose of preventing odour exchange), when taking sandwiches on a journey, or when selling some kinds of take-away or fast food. Tex-Mex restaurants in the United States, for example, typically provide take-away burritos wrapped in aluminium foil.

Aluminium foils thicker than 25 μm (1 mil) are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the production process.

Q:What happens to the aluminum atoms in this reaction?
Aluminum will reduce copper ions (and be oxidized) when chloride ions are present. Otherwise aluminum metal will pretty much just sit there. The reason is the passivating layer of Al2O3 on the surface of any piece of aluminum. This metal oxide layer prevents the metal from actually reacting. But in the presence of chloride ion in water, Al2O3 will react, resulting in AlCl4^- and OH- ions. Al2O3(s) + 8Cl- + 3H2O(l) -- 2AlCl4^- + 6OH- This allows the aluminum metal to come into contact with copper ions resulting in the redox reaction: 2Al(s) + 3Cu2+ -- 2Al^3+ + 3Cu(s) There is a side reaction where aluminum metal reacts with water, and hydrogen gas is produced. 2Al(s) + 2H2O --2 AlOH^2+ + H2(g) When you actually observe the reaction, you will see copper metal being formed, aluminum metal dissolve and bubbles of hydrogen gas being given off. ============ Follow up ============= Because of the passivating effect of Al2O3 and the fact that Al2O3 dissolves in the presence of Cl- forming a new complex ion, AlCl4^-, Brian's answer leaves out a lot of the important chemistry.
Q:Zinc + Sulfur = Aluminum + Sulfur?
1. This depends on the aluminium particle size and it's quality as Al is normally coated with an oxide layer that protects the Al metal underneath. Assuming that the Al powder was good stuff, it should react as violently as the Zn and Mg mixtures. Why .. because it is a very reactive metal ... see further info below. However I needed tried it. 2. The difference is really about the reactivity. Iron, although a reactive metal, is far less reactive than Mg,Al, and Zn. I have tried the zinc and sulphur a number of times and it is really quite violent. With a fair quantityof reactants in the lab it produced an excellent mushroom smoke cloud. I've also seen the Al reactivity demonstrated by a mad Chemistry prof from Nottingham University. He mixed Al powder into a paste with liquid oxygen and ignited it! Wow ... what a reaction.I shall never forget it although it was about 35 years ago!

Q:How do I melt Aluminum cheaply and easily?
Aluminum alloys melt at around 1200 degrees, aluminum cans maybe somewhat lower, but I doubt a tin can would hold up long enough to melt much aluminum, and you would need to be very careful, any moisture in your mold will cause the aluminum to literally explode back into your face. I am not saying it couldn't be done, but you really would need lots of safety equipment before trying it.
Q:Status of aluminum sheet F
The condition code only indicates that the product is in the natural aging stageT heat treatment status (different from F, O, H state) applicable to heat treatment, after (or without) hardening work to achieve stable products,.T code must be followed by one or more Arabia digital
Q:How many square meters does the aluminum plate engrave?
The price of aluminum sheet is calculated according to the price of aluminum ingot + processing fee (aluminum plate state), and the specific price is also different according to the size and size of aluminum sheet. If you have any questions, please ask, thank you.
Q:final temp of aluminum?
To solve this problem, you need the heat capacity of water and Al, I know off hand the heat capacity of water but you'll need to look it up for Al. From the problem, you know that the heat given up as the aluminum cools is gained by the water heating up. As there is no phase change, the heat gained (or lost) is mass * heat capacity * temperature change energy gained by water = energy lost by Al. Let Tf be the final temperature of the Al and water. 32.6 g * 4.18 J/gK * (Tf - 24.4C) = 15.1 g * heat capacity of Al * (53.2 C - Tf) Solve for Tf. Because there is almost twice as much water as Al and water has a higher heat capacity than Al, the temperature will be closer to 24.4C than it is to 53.2C
Q:What aluminum free deodorant works???
Not only does the aluminum in deordorant cause alzheimers, aluminum is also a known carcinogen, and may be a cause to breast cancer ( a lot of breast cancers are first found in the armpit, or close to it.......where deodorant goes.....crazy) i found one at a health food store.... it's called JASON....and it's apricot scented....it works pretty good, just gotta put it on a lot hope that helps!!
